ADHESIVE APPLYING AND REGISTERING MECHANISM Edwin G. Staude, St. Paul,Minn., assignor to E. G.

Staude Manufacturing Minn., a corporation of Minnesota Original No.1,969,106, dated August 7, 1934, Se-

rial No. 492,441, October 31, 1930. Application for reissue June 17,1944, Serial No. 540,791

44 Claims. (or. 93-36) This invention relates to improvements inmachines designed particularly for applying flexible sheets of paper orother suitable material, either glassine, Cellophane, transparent oropaque materials or labels to surfaces of various kinds, and moreparticularly to envelopes or 1 box board blanks, or any other papergoods, or, in fact, to any material which can be fed.

A very important object of. my invention is to provide an improvedmachine for automatically gluing windows in paper blanlm such as arefolded up into cartons; for gluing windows in envelopes, and in bags andthe like, and also for. applying lining sheets of paper material withprecision register.

To accomplish the above, I provide among other features, means forholding thin transparent (or opaque) material, including thin cellulose,Cellophane, etc., substantially under a continuous tension beforesevering, and for thereafter immediately advancing the material to meeta blank to which it is to be glued, and for advancing it at a speedsubstantially equal to the advancing speed of the blank. By this means,

where required; to provide means whereby the provide means forfacilitating drying of the ad-' hesive, to cause quick setting of thesame; to provide a construction known, as the "open side feature, whichgives the operator an unobstructed view of and access to all of the mostimportant mechanisms; and to provide means whereby adherence of thematerial, or sticking thereof to the feeding means (due to production offrictional electricity or static") is reduced to a minimum. v

Other important objects are: to provide means for holding the blank incontact with the adhesive applying device, so that adjustment is notrequired for different thicknesses or sizes of stock Company, St. Paul,

within the range of the machine, with the arrangement 'such as will notpermit adhesive to come in contact with the holding means when for anyreason the adhesive-transferring platen is opposed to the holding meanswhen no blank is in adhesive-receiving position; to provide belt means(as distinguished from cylinder means) for pressing the window, or othersuitable material against the adhesive 01' the blank, toadhesively'connect them, so that in case adhesive is deposited on saidpressure means, the adhesive will not, because of the relatively largearea of the pressing means in direction of feed, be likely to-r'egisteror contact with material which subsequently comes in contact with it tosoil the same; to provide a belt structure (in this instance by groovingin direction of feed) having a substantially reduced working-face areaso that in case adhesive is accidentally applied thereto,

it will be applied over relatively small areas, and.

any adhesive deposited thereon; to provide an airblast and/or equivalentmeans for holding the window-forming or other material in contact withthe pressing belt or means and to use said air blast or other means tocontrol and regulate the suction or pull of the material, before andafter it has been cut. v

A further object is to provide simple means adapted to further controlthe blank, which includes small adjustable trucks which may be quicklyslipped into contact or removed, as required, depending upon the lengthof the blank to be fed into contact over the surface to which it is tobe glued.

Another object of this invention'is to provide a simple timedrelationship throughout the machine from the feeder to the delivery endto insure the accurate predetermined position of the blank and materialwhich is to be glued thereto at all times.

Features of the invention include all details of construction shown,'along with the broader ideas of means disclosed in the present embodiment of the invention.

In the drawings, 2 generally indicates the main frame which consists ofupright side castings connected by suitable crossbars 3. 4 is a spreaderwhich connects the two side frames one to another and supports a bracket5 (see Figures 3 and 8) which supports Cellophane feeding and cuttingmechanisms, as well as the pressing device. 6 is a bracket (see Figure4) which supports the gluing mechanism, and the cam shaft 38, togetherwith the clutchdevice. I are brackets (see Fig ures land 2) which arebolted to the members 2 and 8, and carry the feeding mechanism.

The feeding mechanism consists ofthe usual feed table 8, upon which theblank or material is laid to be fed one at a time by the feed wheel I onthe feed wheel shaft III. A suitable retarding mechanism, generallyindicated at ii, is provided to permit only one blank to be fed at atime. To keep the blank feeding surfaces (usually of rubber) clear fromlint and dust, there is provided a brush I2 which revolves at highspeed, and contacts the feed wheel. Below the feed wheel 9 and co-actingtherewith is a suitable rubbercovered wheel l3. (See Figure 6.)Adjustably mounted on each side of feed wheel 9 are disc wheels il-(seeFigures 2 and 6) having grooves to receive sprocket chains l5, providedwith lugs it. These lugs are so placed and the chains are driven in suchtimed relation that as each blank is fed from the feeder table I, thelugs i8 catch the rear of the blank, and carry it forward into themachine, also in timed relation. The blanksize adjusting mechanismconsists of suitably threaded cross-shafts i1 and I8, on which arerespectively mounted brackets i9 and 29 (see Figures 2 and 6).

A suitable element 21 cross-connects the brackets I. The element 2| isprovided with side guides 22 and 23 (see also Figure 1) which areadjustable and which engage the sides of the blank to maintain itsparallelism to line of feed. Other guiding and controlling rods areindicated at 24, and act to hold the blank upon the feeding chains l5.Suitable idlers 25 are provided, along with means for adjusting them, totake up the slack in the chain ii. The grooved pulleys l4, and therubber-covered pulley 13 are mounted on a shaft 26, which is driven by asprocket 21 through a chain 28 from the shaft 29, see Figures 1 and 2.

A spur gear 30 (see Figure 6, also Figure l) is mounted on the shaft 26and drives a spur gear 2|, which in turn drives the feed wheel shaft I0.Suitable grooved pulleys 32 on the shaft l0 and 33 on the shaft 34(which carries the brush 12) have the driving connection 35, and-thusthe brush I2 is operated.

Referring to Figures 1 and 4: 36 is the main drive shaft and transfersmotion to the shaft 31. The shaft 31 is in turn geared to the shaft 38,also to the shafts 29, 39 and 40. The'shaft 39 is geared to the shaft 4|and the shaft In is geared to the shaft 42. The shafts 39 and 4| havefeeding collars 43. This is also true of shafts 40 and 42. The locationof these feeding collars 43 is such that they advance the blank throughthe machine without coming in contact with the adhesive.

A feature of the invention relates to means i fer dies of differentareas can be attached on the gluing drum for applying glue at anydesired location on the article. Referring to Figures 4, 1'1, 19 and 22:There is provided a semi-circular drum 44 (Figure 17) to which issecured a plate 4! for circumferential adjustment. The plate is held forsuch adjustment by means of beveled elements 49. Clamp member 41 has acorresponding beveled element and is secured by cap screw 48. On plate4| is a curved zinc etching plate 49, see Figure 18, held in place byscrews 59, engaging screw-threaded sockets or openings of thecircumferentially adjustable plate 45. The screw holes are placed aboutthree-quarters of an inch apart and are in regular rows at right anglesto one another, see Figure 22. By this arrangement, it is clear that thegluing die 49, which is usually a die-cast metal plate, is first mountedon the master plate 49 in any one of a plurality of positions. Thisplate 49 is one of a series of plates of different areas or sizes whichcan be attached to plate 45. The plate 49 can then be circumferentiallyadjusted and then clamped in the correct position by means of the capscrews 48. The drum 44 can then be adjusted transversely of the feed bysliding along the shaft 28. When it has reached the proper position forapplying adhesive, it is clamped by screw 55.

By using a curved zinc etching plate as an adhesive impression orprinting member, theadhesive can be accurately printed or applied, andby substituting various printing plates the adhesive can at smallexpense be applied over any desired area and have any desired contour.In order to hold the blank 5| against the zinc plate 49 to feed it andcause it to be properly held while it receives adhesive, shafts i2 and59 (see Figure 17) are arranged, in this instance below the drum 44, andparallel with its axis of rotation, the shafts being arranged laterallyof a vertical line passing through the axis of rotation of the drum. Theaxes of thedrum and shafts are related substantially as the corners ofan isoscelestriangle. Each shaft has attached thereto or integrallyformed therewith a series of spaced disks 54, see Figure 18. The workingfaces of these disks extend slightly above the level of the line offeed, and provide a plurality of spaced narrowsurfaced contacts adaptedto engage the under side blank, hold it in printing position and feedit. The areas of these surfaces are reduced to a minimum so that if glueis accidentally deposited thereon, the quantity which they will receivewill be very small, and so that a very much smaller quantity will betransferred to the bottom of a subsequently fed blank, .as in a casewhere a blank is not lnthe position shown in Figure 17 when the printingelements 49 assumes the position shown in that figure. By using thedisks and having their peripheries crossing the line of feed, indirection of the drum, and by arranging their axes of rotaitionlaterally of a line passing through the axis of rotation of the drum 41,the peripheries ofthe disk are so placed that they will never comedirectly in contact with the adhesive-covered surface of the element 49and, therefore, only in rare cases will any adhesives be transferred tothe disks. If it is so transferred, it will be in very small quantity,so that a correspondingly small quantity can possibly be transferredfrom the disks to the bottom of the blank 5! and therefore a very smallquantity can be transferred from the bottom of the blank, to

the feed rolls 48 or vother feeding elements of the mechanism. This is avaluable feature of the invention. I

In order to apply. the adhesive to the blank, a

certain amount is transferred to theraised portion of the curved platefrom thetransfer drumll,seeFigure4. Ifthedisksflwereplaced directlyunderneath the curved table. then the space between their peripheriesand the curved plate would have to be slightly less than the thicknessof the stock. Stock, of course, varies in thickness. and for runningthinner stock, the

disks '4 would be so close that when the machine was operated withoutfeeding any stock, the adhesive would be transferred from the curvedplate 49 to disks 54. This is very objectionable because when the nextblank is fed, the adhesive on the disks 54 is transferred to theunderside of the blank BI and gums up the rolls 49 on the shafts 49 and42,and also gums up the belt 99, besides spoiling the stock. By placingthe disks 54 in the position shown in Figure 17, that is. one roll oneach side of the vertical center line of the shaft 39, and raising thedisks 54 slightly above the work line, stock of practically anythickness can be run and with no gumming and spoilage of stock, asaforesaid. In fact, with this construction the spade between the disks94 and the curved plate 49 can readily be two or three times thethickness of the blank 5| and still hold the blank against the surfaceof the plate 49 firmly enough to positively properly transfer theadhezinc plate 49 will not come in-contact with the disks 54 on theshafts 52 and 53, but has ample clearance, equal at least to thethickness of the stock so that when a subsequent blank is fed there willbe no offsetting or transfer of adhesive 10m the disks 54 to theunderside of the blank Since these disks 54 (which are really turned onthe shaft) can extend the entire width of the gluing surface, it followsthat after once the proper relationship is established between theshafts 52, i3 and 98, no attention need ever be paid to the shafts l2and 53, even though the outline of the plate 49 is varied throughout therange of the machine.

The sector member 44 is clamped to the shaft 99 by means of a cap screw55 andcan be ad justed laterally on the shaft, and the beveled surfaces49, already described, permit circumferential adjustments of the plate45 and glue printing element 49. A spline 99 prevents rotation of member44 on shaft 38, but permits lateral adjustment.

The glue supplying means includes a glue pct 91, having a transfer drum58 '(see Figure 4) rotating in the glue, and a transfer drum 59 deliversthe glue to the plate 49. Both the transfer drums 58 and are mounted inoverhead bracket 62 which is bolted to a spreader 69, secured to theside frames 6 by means of a cap screw 6|. A beveled or tapered slot 69is provided in the spreader 99 to permit adjustment crosswise of themachine. The flow of adhesive is controlled through suitable adjustingscrapers shown at 94. The location of the transfer drum 59 is such thatthe zinc etching 49 will just clear the transfer drum 59 and receiveadhesive therefrom.

The shafts 52 and 53 are provided with suit- 'able bearings 85 (seeFigures 22 and 23) and have suitable smooth, flat pulleys 63, driven bya rubber covered wheel 01, which is mounted on the shaft 38 and revolvestherewith. The bearings for the shafts 02 and 03 are mounted in abracket 69 which is clamped-on a spreader shaft 3. The shaft 33 alsocarries the clutch or throwout mechanism I (see Figures 19, and 21)which consists of a member II, secured to the shaft 33 by a key I2 heldin place by a set screw 13. Member II has a groove I4 adapted to receivethe arcuate part I0 on the clutch arm I8. A clutch pin 11 is held in theon position by the spring I8, which in turn is kept in place by a plateI9. The spring causes the clutch pin 11 vII9 by a suitablebracket I20,clamped in posito be moved into the path of'the pin 90, secured to themember II, which carries the paper regulating cam 32, and the rollfeeding cam 93, and

means, not shown, and the member 3|, theretau? lugs I8 on the chain I9,delivering the blank to the collars 43 on the shafts 4| and 39, applyingthe adhesive through-the action of the zinc etching 49, while the blankII is being held in contact by means of the members 94. then feeding theblank III into the collars 43 on the shafts and 42. The blank thenpasses to the endless belt or carrier 99, which is driven by the drumI00 on the shaft WI, and is held down on the belt 99 by asuitable topcarrier mechanism II3, see Figure 2. This mechanism consists of a seriesof idler rollers'which bear on the upper surface of the blank, and issecured to a shaft tion by the stud III. The blank next passes undemeaththe grooved belt 93, which feeds down the second-material to be glued,as hereinbefore described. I

These bushings are provided with suitable lubricating The mechanism forfeeding the material to be glued, cutting the same, and causing it toregister with the aforesaid blank as it passes through the machine is asfollows: A roll of stock I22,

fore, onlyrevolves when the clutch pin 11 is in Q similar to clutchesusually provided for this purpose, but the purpose of this clutch is tostop the cutting mechanism, the feeding mechanism, and the mechanism fortaking up the slack to permit continuous pull on the roll.

The shaft 33 is provided with a sprocket 91 and has a bearing in themember 93 which is a part of the bracket 6 and is driven by the spurgear 99, which is keyed at 90. The sprocket 0] drives the shaft 9| (seeFigure l) which carries the pulley or drum 92 (see Figure 3) over whichsuch as glassine paper, Cellophane or'other material, is placed on aspindle I23 (see Figures 1,

2 and 7), the spindle being mounted in brackets I24 and I25. Suitabledisks I29 and I2I are adjustable on each side of the roll I22 to keep itin position (see Figure 1). A friction strap I23, having a weight I29,and pivoted at I30.

i' rests over the outer periphery of the roll I22 and keeps it fromover-running, so that no slack will accumulatefrom the roll as it is fedthrough the machine. 1

Means for continuously rotating or revolving the supply roll to preventaccumulation of slack,

is an important feature. The present means for accomplishing thisoperates so that when the feed rolls are at their maximum speed, atension arm I39 is at minimum speed, but the arrangement is such thatthe arm I39 has a continuous motion in a manner to exert a continuouspull on v the strip and cause the reel I21 to move conthe grooved belt93 is stretched around the idler 94, mounted on a suitable shaft 39 andhung on an arm 90, pivoted at 91 in an adjustable sliding box 99.Referring to Figure 4, after the blank has received the impression ofadhesive, and has passed between the collars 43 on the shaft 42 andmember 44, it then passes on to anendless carrier belt 99 which isdriven by a drum I00 on a shaft "I that is driven from the train ofgears (not shown)- that drive the shaft 40. The

belt 99 is supported by suitable idler rolls I02,

andthe belt-tightening mechanism I03, I04 and 1 by set screw I08. Thebelt 99 passes over a a pulley I09 and all of the idler pulleys and thepulley I09 are mounted in suitable frames IIO (see Figure 8) which arecarried by brackets III and clamped on the cross shaft 3. A suitableconveyor belt H! (see Figure 1) is provided, consisting of a drum 3,around which the conveyor belt II 2 passes, the drum being driven by agear' reduction mechanism, generally indicated at II4, driven by asprocket Hi from a sprocket IIS on the shaft 9I, through a chain I I1.

tinuously. This is a great advantage over the old gravity-operateddevice which put such tensile strain on the paper that it was frequentlyirregularly torn or broken.

The material I3I (see Figure 3) is-threaded down through a guide slotI32, and between two The foregoing description includes the mechand I.

bars I33 and I34. These bars are mounted on an oscillating arm I35 andsecured to a shaft I30 that contains the slot I32. To provide anoscillating motion for the shaft I36 (see Figure 1) a depending arm I31is provided, the end of which is connected with a pivotingrod I30 thatis connected to an eccentric strap I39 on the eccentric 32 (see Figure19). The eccentric 32 Is set in the proper synchronizing relation toeccen-' tric 83, which operates the adjustable feeding mechanismhereinafter described, so that as the feed rolls I40, I (see Figure 3)feed the material I3I downwardly at the maximum speed,

the slack will be "paid in by the rods I33 and I34, and as the feedrolls slow down to the stopping position, the rods I33 and I34 willswing outwardly and in that way cause practically a continuous rotationof the roll I22. The material I3I is fed down between the feed rolls I40These rolls have asmall groove in the center adapted to receive tonguesI42 and I43 to facilitate in threading the stock down between the frameandgu ide members I44 and*l45.

A stationary cut-off knife I46 is provided having a movable cut-offknife I41 co-acting there- 1 with. Suitable adjusting screws I40 and I49are provided for adjusting the'knife to the proper lap.

Other guides for the material are provided below the knife, as indicatedat III and III. If the material were fed directly against the belt 88(which is preferably composed of a rubber and canvas composition), thegrab or suction would be so greatthat it would draw the stock betweenthe rolls I40 and I, and if these rolls were set so tight that the stockwould not draw, then the stock would not feed down in parallelism,butwould become wrinkled when passing through these feed rolls. If the belt93 pulls too hard on the material vIll before it is cut oil, it willtear during the cutting operation, that is the knife begins cutting onone edge, according to the shear" principle, and before the material iscut oil, and if the suction is too great it tears at an angle, which isvery objectionable.

Another feature, therefore, is the use of a rubber and/or grooved lbeltas a feeding means, and as a means cooperable with the blank-advancingbelt to press the registered material, which type of belt has greatertraction capacity, and when grooved reduces the freezing" effects ofstatic. Another important feature is this particular kind of a belt incombination with some means for lightly holding the material against theworking.

surface of the belt, either by the use of gravityactuated roller, or byan air blast, and/or with means for varying the area of contact.

An adiustable shieldor visor I! is provided to keep the material I8Iaway from the-belt 98, except for a distance equal to two rolls I53,- inthe truck I54. This visor or shield I52 extends clear across the belt 93that is provided with grooves I55 (see Figure 12). The shield I52 has alateral flange, which is pivoted as at I55 to bracket I51 bolted to theframe I58 (see Figures 2, 7, 8 and 16). In order that the pivot I55shall be concentric with the shaft 9|, a stud I59 is provided (seeFigure 16), which extends in a socket I80 in the end of the shaft 9|.Since the shaft 8| revolves, and because of the difllculty of pro,-viding proper lubrication, and in order that the stud I59 will notfreeze to the shaft 9|, a wood bushing I5I is provided. This bushing isspecially treated material soaked in oil and therefore requires nolubrication, since there is little load on the bearing at this point.Since the visor or shield I52 is pivoted at the point I'55, it can beswung around the drum 92 concentrically with the belt 93 into anydesired position, to regulate the amount of material I3I which is to bedirectly opposed to the face of belt 93. To accomplish this regulatingadjustment, a hand wheel I52 is provided, adapted to tighten up on abelt I58 and clamp the member I52 against the bracket I51. A concentricslot I84 is provided in the casting I51, through which slot, bolt I53carried by the visor or shield I52 passes. After shield ad- Justment,the same is securely clamped by wheel Each small idler wheel I53, in thetruck I54, has a shaft I55 (see Figure 7) rotatably stepped inthe'inclined slots I65 of the plates. Each slot is L-shaped with adownwardly directed portion spaced a greater distance from the peripheryof the belt 93 than the other portion of the slot. Each shaft may,therefore, be rolled in a direction away from the face of the belt todrop into this downwardly directed portion, thereby preventing its wheelor roll I53 from contactingthe material I3I or belt 93. In this way, therollers can be selectively positioned, and as many used as desired. Thetruck I54 is adiustably pivoted on the shaft I88, and is clamped to theshaft by hand wheel I89, see Figures '1 and 12. In order to provide whatmay be termed a universal adiustment for the shaft I88, and the truckthereon, for bodily moving them vertically and horizontally, and forrotating the shaft, the shaft is non-rotatably attached to member I59(see Figures 12, 13, 14 and 15) and is rotatably journaled in plate ill,see Figure 15, as at I10 so that the shaft can be rotated when plate I59is adjusted. Plate III is pivoted as at I12 to member I14 and may swingtoward or away from the belt 93 to correspondingly bodily move the shaftI88 and the truck i54 thereon. 'For this purpose, the member I14 isprovided with a slot I13, and the member I89 is provided with a slotI18. A

stud I11 extends through these slots andis secured in the member "I andhas its opposite ends threaded as shown in Figure 14. The hand wheel I15engagesthreads I15 to clamp the plate I59 in adjusted position and hand'wheel I19 engages with the threaded portion I80 to co-act with thebracket member I14 to secure the plate MI in adjusting position. Theslot I13 is also shown in Figure 13 in dotted lines and it wi l be notedthat the slots I18 and I13 are angularly related, so that vertical andhorizontal adjustment of the element I88 may be obtained, by properlyma-' This is of great advantage because if there is any appreciabledelay in the motion of the material toward the registration point,accurate registration is imposible. It is notorious in machines of thisclass that a large amount of material is wasted because of poorregistration or failure of registration at thispointj As hereinpracticed, the material can be held in light but continuous contact withthe feed and pressure belt. Heretofore, various devices have been usedsuch as providirig a stop for the material, \but this is not applicableto flimsy materials. The maintaining of a light and continuous tensionis an important feature, as is the ability to vary the degree oftension, as well as the area of contact, and the ability to apply thecontact nearer or farther away from the severing point of the material.

The shafts of the rolls I53 can be easily raised from the slot portionsI51 and put into operative relation, or'v'ice versa, and thus the areaand degree of contact can be varied.

Frequently the material I3I is very thin and apt to curl; I havefoundthat a light blast of air may be employed to hold it against the visorI52 or against the belt 93. For this purpose, a small electric fanI8I'is used and is driven by a motor I82 adjustably mounted as at I83 todirect the blast at any required angle, the motor being driven by theusual electric connection.

As is common in feeding web stock, a great deal of static electricity isgenerated, and when this comes in contact with a non-conductor, such asthe surface of the. belt .93, it follows that it adheres to such surfaceso strongly, that it is with great dlfllcuity that winding is prevented.It is true that there is "tack" in the adhesive that is printed on theblank, and with which the material III is intended to match up and stickto, yet the tack" is frequently not sufficient to cause the material I3lto stick to the blank, yet it will adhere the belt 93 and windtherearound. If the amount of tack in the adhesive is increasedsufficiently to hold the material I8I, then the adhesive is so tacky asto cause stringing" and in a short time the glue will be'transferred togum the entire machine.

I have devised a means for reducing the static effects by fifty percent, to-wit: by cutting grooves in the belt 99, so that the contactarea is propor- 'the required amount, and in that way greatly tionatelyreduced without adversely affecting the pressing or feeding function ofthe belt 99 relative to belt 99, to obtain perfect adhesion of thematerial I3I to the blank. The grooves, therefore, reduce the static byfifty per cent, provided their aggregate area is equal to the contactarea. The grooves may be utilized to receive wire stripper members whichcan be threaded therein to prevent the material I3I from winding orsticking by means of static, but it has been found that with a reductionof fifty per cent in static effects, this winding is practicallyentirely eliminated, and, therefore, no stripping means is shown. Thegrooves also have the advantage of reducing the working area of thebelt, so that if adhesive is accidentally applied, the quantity which itcan receive is reduced by fifty per cent.

Another valuable feature is that with the light contact made by therolls I53, slippage may .take place between the material and the belt 93so that there is never sufficient pull on the material to cause it totear unevenly while being cut, particularly when the shearing method ofcutting is used.

It is contemplated herein to use a fan or-equivalent air blast formaintaining contact of the fed Cellophane or like material with thebelt, or to use the light roller contacts I53 separately, or to usethese means in combination.

There is also a decided advantage in using a belt instead of a rubbercovered drum (92), because it is easier to so time the machine that incase glue reaches the belt at any particular point, this glue will notbe so likely to register at some later time with the material I3I as itis fed, until possibly after a considerable number of revolutions duringwhich time the adhesive (which is of the quick setting variety) willhave so dried to such an extent that it will not be likely to stick tothe material III. In addition, the use of the grooves so reducesthe'possible area of contact of the glue that it even more quickly driesand flakes and drops off. Therefore, by the use means is reduced to anegligible minimum.

Referring to Figures 1 and 8, it is to be noted that the Cellophanefeeding, cutting and registration mechanism is arranged so that everyim-,

portant part can be directly viewed by the operator as he stands at theside of the machine. Moreover, all the adjustable working parts arereadily accessible, particularly the rollers 'I 55, and the adjustingmeans for the shield I52, see also Figure 7.' The adjusting means forthe truck I54 is also readily accessible.

I have also discovered that when the fan IN is set at a certain angle,for short work, and the shield I 52 is raised practically out of contactwith the material I8I,.the blast of air flowing in the grooves I55 tendsto reduce the suction to Just assist-in controlling the material III asit passes down into contact with the blank to which it is to be secured.

Themechanlsm for operating the cut-oil'knife, and for intermittentlydriving the feed rolls I48 and I, is as follows: The feed roll I48 ismounted oh a shaft I84, and the feed roll MI is mounted on a shaft I85.These shafts have suitable bearings I88 and I81, see Figure 7. Theroller I48 is held in contact with the roller I by a spring I88 pressingagainst the bearing I85, and in order to initially pass the paperbetween the feed rolls I48I4I, a small cam arrangement, generallyindicated at I89, is provided, the raising of which separates thebearing I88 from the bearing I81, and correspondingly separates the feedrolls.

Other bearings are provided at I98 (see Figure 8). Gears I9I on theshafts I84 and I85 establish a driving connection between the rolls I48and MI. Referring now to Figures 8, 9, 10, 11, the means for operating.the feed roll shafts includes a gear and rack mechanism, comprising agear I92 driven by a rack I93, the rack being pivoted at a point I94,and motion to the rack being obtained through an addustable connectionI95, and aconnecting rod I95, see Figure l, which, in turn, is connectedto the eccentric strap I91 (also see Figure 19) motion to which is givenby the eccentric 83 on the shaft 38. Byv adjusting the clampingconnection I95 in the slot I98, the stroke of the member I95 can bevaried, and, therefore, of course, the degree of rotation of the shaftsI84 and I85. Each shaft I84, I85 has a gear I92, and connected to eachis adisk I99 (see Figure 11) carrying a series of ratchet dogs 288.These ratchet dogs are held into contact with a ratchet wheel 28I bysprings 282. The ratchet wheel 28I is keyed to the shaft I84 and asimilar mechanism to the shaft I85. The teeth in the ratchet of onemechanism are in a direction to feed the material I3I between the rollsI48 and HI downward and slip over the other corresponding ratchet. 0nthe return stroke the opposite ratchet takes effect and the first oneslips, so that rotation of the shaft I84 in the direction of the arrow(see Figure 9) is accomplished by the connecting rod I95 moving in onedirection, and rotation of the shaft I85 in the direction of the arrowis accomplished by the movement of the connecting rod I95 in theopposite direction.

The purpose of this is to make use of both the forward and return strokeon the eccentric to members and is kept under yielding tension by aspring 285. to a part of the frame on the machine at 285. g

This brake member is fastened The purpose of this brake is to preventoverrunning" and the tension is adjusted so that when the gears I92reach their maximum stroke, the ratchet 28I will not over-run andthereby cause an un-uniform length of material I8I to be fed. Thismechanism for cutting off the material I3I at the dead center point ofthe eccentric 83 is raised portion is so timed that it will strike theroller 2|. and operate the arm Ill and with it the connecting rodflll.This rod 2III is connectedto an arm 2, which inturn issecured toa shaft2I2,see1"igure3.,.'1heshaft 2i! ismounted on a suitable bearing and hasdepending arms 2ll, pivoted as at 2 to casting 2I5 that supports theknife I41.

vide a spring 2i! between lugs 2" on the arm Ill, and lugs 2" on themember. 2I5. From the description, it is clear that as the cam 54 withthe projection 201 revolves in timed relation to In order to keep theknife I I41 in shearing contact with the knife I4, I proover the surfaceof the shield I52, the first few strike the roller 202 when theeccentric "is at dead center, it will produce a short, quickreciprocating motion of the arm and through the connections described,operate the knife I41 and cut the material Ill. In order to get exactadjustment, so that this motion will take place absolutely on deadcenter, I provide an eccentric bushing 2i! (see Figures 5 and 21) at thepivot of the arm 20! and secure the eccentric bushing into position by aset screw 220. As the bushing 2" is revolved, it raises or lowers thearm 20! and thus regulates the time accurately in which the raisedportion 251 on the cam 84 strikes the roller 202.

For the purpose of operating the clutch arm 12 (see Figures 1, 4 and 20)there is provided a shaft I I9 which supports the fork mounting 222 (seeFigure 1) for the arm 18. It also supports the shaft 222, on which ismounted a depending arm 224 (see Figure 4), hav ng an inclined radialrollers I52 directly over the shield I52, are placed in the rear of theslot I", the lower part of which is indicated by the reference figureI61, and are, therefore, inactive. As the material continues to be feddownwardly it comes in contact with the grooved belt 92, which isoperating continuously, and acts as a continuous feeding means. At thispo nt, the rollers I53 are set out into the opposite position in theslot I" on the member I54 and serve to bear the material III against themoving surface 93. From this description it is clear that the materialIii is kept under tension continuously because the speed of the surface93 is much faster than the speed of the rolls HI and I42. By tilting thefan III at the properangle additional pressure may be obtained asrequired.

Since the feed rolls HI and I42 are driven intermittently, it followsthat the cut-off knife surface 225. The inclined surface 225 isadaptedpast the gumming or gluing mechanism on this belt" strikes the inclinedsurface 225, element 224 will be raised and shaft 223 oscillated to inturn rock the opposite end of the member 224 at 228 (see Figure 4). Thismember is connected to a depending arm 229 on the member 16 by a rod230. Therefore, when the blanks pass through the machine continuously,the arm 224 will at all times keep the arm 15 raised, and consequentlythe inclined surface 15 (see Figure 11) during the time when the pin 11passes this part 15 and, therefore, will have no action on the pin 11,and the machine will operate continuously. Should, however, the blanksnot be dellvered to the belt 99, the inclined surface 225 of thedepending arm 224 assume the position shown in Figure 4 and cause thearm 16 to drop into the groove 14 and withdraw the pn 11, and therebyde-clutch the mechanism that controls the eccentric 82-83 and cam B4,and these members will remain inoperative until a blank is delivered, atwhich time shaft 223 is moved to raise the member 18, release pin 11 sothat it again engages pin 80.

The operation of the machine is as follows: Blanks are placed in thefeeder 8; the feed wheel 9 in revolving, picks 011 one blank perrevolution and carries it out over the top of the chain II. Lugs It onthe chain catch the rear of the I41 must operate during the period thatthe eccentric I81 is passing over a dead center. At this point, theprojection 201 on-the cam 84 strikes the roller 20! and rocks the knifeinwardly and cuts off the material -l3l, which has been fed down to apredetermined length, as hereinbefore described. Directly that thematerial is severed and being in perfect contact with the moving surface93, it immediately takes on the surface speed of the belt 93 and meetsthe blank to which it is to be pasted, in timed relation at the point ofcontact of the belt 93 with the belt 99. Since the shield I52 isadjustable for different lengths, it is clear that the shield can berocked counter clockwise and give the rollers I53 a chance to contactwith the material III earlier in the cycle of operation by merelylifting the rollers I53 out of the space I61 and permitting them to rollby gravity to the opposite direction in the slot I.

It is, of course, obvious that this machine may be set in front of anyfolding box refolder and gluing machine; and belted as one unit, so thatthe entire operation of applying transparent material over the windowsof cartons, refo1ding,'

gluing, folding, counting and stacking may be accomplished in oneoperation. In fact, the mablank and carry it forward in timed relationto be received by the collars 52 on the shafts 22 and H. The blank thenpasses. over the rolls 84 and receives the imprint of the adhesive fromthe projection 49 in the proper position. It is then advanced betweenthe rolls 42 onthe shafts 40 and 42. The blank next passes between thebelt II and the pressure carrier I it. During this time,

chine is now so constructed that either the conveyor II2 can be used, orit may be removed and the machine will then deliver the blanks directlyto a folding box gluing machine.

Another important feature never before accomplished in a. machine ofthis kind, are the various arrangements bywhich the machine can bequicklyset for different sizes of blanks. In other words, the greatadvantage is provision of means for obtaining a large size rangeadjustment, and for obtaining it quickly.
